ExternalStructure question

Hello,

If I have the following structure:

 typedef struct {
  char **FNV;             = Think of this an argv
 } zcl.

How do I have to define the field for this? This seems to be a Pointer
to a NULL terminated Array of Pointers to NULL terminated strings.

I used PointerArrayPointerField but neither the length of the array nor
the legth of the strings is known.

Any ideas/workarounds?

Thanks,

Udo
